Abstract (en)
[origin: EP1262698A2] An expansion valve 1 comprises a piping member 10 equipped with passages to which refrigerant pipes are connected, and a cassette unit 100, the two members being formed as separate units. The cassette unit 100 comprises a tube member 110 having a flange portion 111, and at the interior of the tube member 110 are fixed a guide member 170, an orifice member 180, and a plate member 166. The pressure of the gas filled in a gas charge chamber 122 defined by a lid 120 and a diaphragm 130 displaces the diaphragm 130, the displacement being transmitted through a stopper member 140 to a shaft member 150. The shaft member 150 is guided by a guide member 170 and controls the valve means 160 inside a valve chamber 161. The cassette unit 100 is inserted to the pipingmember 10 and fixed to position by a ring 50. Seal members 62, 64, and 66 are equipped to appropriate areas between the cassette unit and the piping member. <IMAGE>
